ChatGPT Has Been Integrated Into a Brain Implant (cnet.com) 34

CNET visits a leading-edge company making an implantable brain-computer-interface that's "experimenting with ChatGPT integration..." We previously covered Synchron's unique approach to implanting its brain-computer-interface (BCI) without the need for open brain surgery. Now the company has integrated OpenAI's ChatGPT into its software, something it says is a world's first for a BCI company...

Typing out messages word by word with the help of a BCI is still time consuming. The addition of AI is seen as a way to make communication faster and easier by taking in the relevant context, like what was last said in a conversation, and anticipating answers a person might want to respond with, providing them with a menu of possible options. Now, instead of typing out each word, answers can be filled in with a single "click." There's a refresh button in case none of the AI answers are right... [ALS patient Mark, one of 10 people in the world testing Synchron's brain implant in a clinical trial] has noticed the AI getting better at providing answers that are more in line with things he might say. "Every once in a while it'll drop an f-bomb, which I tend to do occasionally," he says with a laugh.

Synchron CEO Tom Oxley tells me the company has been experimenting with different AI models for about a year, but the release of OpenAI's ChatGPT-4o in May raised some interesting new possibilities. The "o" in ChatGPT-4o stands for "omni," representative of the fact that this latest version is capable of taking in text, audio and visual inputs all at once to inform its outputs... Oxley envisions the future of BCIs as... having large language models like ChatGPT take in relevant context in the form of text, audio and visuals to provide relevant prompts that users can select with their BCI... Synchron's BCI is expected to cost between $50,000 and $100,000, comparable with the cost of other implanted medical devices like cardiac pacemakers or cochlear implants.

A New HIV Prevention Strategy Sparks Excitement - and Protests Over Cost (npr.org) 47

"Lenacapavir is not a new drug," reports NPR. "It's been approved by the FDA in the United States for multi-drug resistant HIV treatment since 2022."

But instead of treating HIV, what if it were used for preventing infections? The treatment consists of a twice-yearly injection... Early trial results were released in June and generated great excitement, indicating 100% efficacy. On Wednesday, July 24, the full peer-reviewed results were released at the AIDS 2024 conference, confirming the preliminary data... This treatment offers an alternative to the current standard of core for HIV prevention efforts for over a decade: taking a pill like Truvada every day...

Any eventual approval and widespread use would come with challenges... Lenacapavir's cost as HIV treatment in the United States in 2023 was $42,250 per new patient per year. Oral PrEP options, on the other hand, can cost less than $4 a month. "The biggest gap in prevention isn't medication, it's accessing medications," says Dr. Philip Grant, clinical associate professor and director of the HIV clinic at Stanford University School of Medicine.

Activists across Uganda and South Africa have urged Gilead Sciences to license lenacapavir to the Medicines Patent Pool — a United Nations-backed organization that partners with governments, industry and other organizations to license medications. This would allow for manufacturing of generic versions of the drug at a fraction of the cost... [A] group of Médecins Sans Frontières activists gathered at AIDS 2024 and called for an "immediate global action to break Gilead's monopoly on lenacapavir."

In a statement Gilead said they couldn't set a price because the drug had not yet been approved — but that Gilead "is committed to access pricing for high-incidence, resource-limited countries." Gilead will ensure dedicated supply of lenacapavir for HIV prevention in the countries where the need is greatest until voluntary licensing partners are able to supply high-quality, low-cost versions of lenacapavir.â

Gilead is developing a robust direct voluntary licensing program to expedite access to those versions of lenacapavir in high-incidence, resource-limited countries. We are moving with urgency to negotiate these contracts.

Sharks Near Brazil Test Positive For Cocaine (bbc.co.uk) 40

RockDoctor (Slashdot reader #15,477) writes: The BBC are reporting sharks have tested positive for cocaine. Thirteen sharpnose sharks which were captured off the coast near Rio de Janeiro. They were tested for the drug in liver and muscle tissue samples — and returned positive results at concentrations as much as 100 times higher than previously reported for other aquatic creatures.

The research was published in Science of the Total Environment. The little-known "sharpnose" sharks were examined because they spend their entire lives in coastal waters. This makes them more likely to be exposed to drugs from human activities than the more cinematic species starring in "Cocaine Shark" or "Cocaine Sharks", two recent productions on the subject featuring hammerheads and tiger sharks (the "trash cans of the sea").

The likeliest source is effluent from drug processing labs inland, though the snorting population of Rio may have added their contribution into the sewers too...

Whether cocaine is changing the behaviour of the sharks is not known. Perhaps it would affect their aim with their head-mount lasers, bringing closer their conquest of the land with it's tasty, tasty humans. Hollywood, hopefully, as the answers.

NASA's Mars Rover Detects 'Building Blocks of Life' in Rock (msn.com) 19

"Scientists working with NASA's Perseverance rover state emphatically that they are not claiming to have discovered life on Mars," writes the New York Times.

"But many would regard a rock that the rover just finished studying as 'Most Likely to Contain Fossilized Microbial Martians'..." The rover has drilled and stashed a piece of the rock, which scientists hope can be brought back to Earth in the coming years for closer analysis and more definitive answers. "What we are saying is that we have a potential biosignature on Mars," said Kathryn Stack Morgan, the mission's deputy project scientist. She describes a biosignature as a structure, composition or texture in a rock that could have a biological origin.

The rock, which scientists named Cheyava Falls, possesses features that are reminiscent of what microbes might have left behind when this area was warm and wet several billion years ago, part of an ancient river delta. The scientists clarified that they did not spot anything that they thought might be actual fossilized organisms... Within the rock, Perseverance's instruments detected organic compounds, which would provide the building blocks for life as we know it. The rover also found veins of calcium sulfate — mineral deposits that appear to have been deposited by flowing water. Liquid water is another key ingredient for life. Perseverance also spotted small off-white splotches, about 1 millimeter in size, that have black rings around them, like miniature leopard spots. The black rings contain iron phosphate.

The chemical reactions that created the leopard spots could also have provided energy for microbes to live on.

"One of the key parts of Perseverance's mission is to drill samples of interesting rocks for a future mission to bring samples back to Earth for scientists to study with state-of-the-art instruments in their laboratories," the article points out. And while exactly how those rocks would be return has yet to be determined, deputy project scientist Morgan tells the Times, "I think this sample comes to the top of the list."

Boeing Starliner Astronauts Have Been In Space Six Weeks Longer Than Originally Planned (arstechnica.com) 51

Longtime Slashdot reader Randseed writes: Boeing Starliner is apparently still stuck at the ISS, six weeks longer than planned due to engine troubles. The root cause seems to be overheating. NASA is still hopeful that they can bring the two astronauts back on the Starliner, but if not apparently there is a SpaceX Dragon craft docked at the station that can get them home. This is another in a long list of high profile failures by Boeing. This comes after a series of failures in their popular commercial aircraft including undocumented flight system modifications causing crashes of the 737 MAX, doors blowing out in mid-flight, and parts falling off the aircraft. The latter decimated a Toyota in a populated area."I think we're starting to close in on those final pieces of flight rationale to make sure that we can come home safely, and that's our primary focus right now," said Steve Stich, manager of NASA's commercial crew program.

"Our prime option is to complete the mission," Stich said. "There are a lot of good reasons to complete this mission and bring Butch and Suni home on Starliner. Starliner was designed, as a spacecraft, to have the crew in the cockpit."

NASA Fires Lasers At the ISS (theverge.com) 28

joshuark shares a report from The Verge: NASA researchers have successfully tested laser communications in space by streaming 4K video footage originating from an airplane in the sky to the International Space Station and back. The feat demonstrates that the space agency could provide live coverage of a Moon landing during the Artemis missions and bodes well for the development of optical communications that could connect humans to Mars and beyond. NASA normally uses radio waves to send data and talk between the surface to space but says that laser communications using infrared light can transmit data 10 to 100 times faster than radios. "ISS astronauts, cosmonauts, and unwelcomed commercial space-flight visitors can now watch their favorite porn in real-time, adding some life to a boring zero-G existence," adds joshuark. "Ralph Kramden, when contacted by Ouiji board, simply spelled out 'Bang, zoom, straight to the moon!'"

Childhood Air Pollution Directly Linked To Adult Lung Health, Study Says (theguardian.com) 28

Air pollution breathed in during childhood is one of the factors in adult lung health, according to a new study. From a report: The origins of the study date back to 1992 when researchers began investigating the effects of air pollution on groups of children in California. Some of these children are now in their 40s. Dr Erika Garcia and colleagues from the University of Southern California decided to see how they were getting on. More than 1,300 people replied and filled in detailed questionnaires on their income, lifestyle (including smoking), homes and health. This was matched against their childhood health and the local air pollution when they were growing up.

The first finding was that people with higher childhood exposures to particle pollution and nitrogen dioxide had a higher likelihood of bronchitic symptoms as an adult. This relationship was strongest for those who had developed asthma and lung problems as children, meaning these people had a vulnerability that continued into adulthood. The second finding was unexpected: a relationship existed between childhood air pollution and adult bronchitic symptoms for people who did not have lung problems as children. This suggests the damage from air pollution in childhood may only manifest in adult life. Garcia said: "This was surprising. We thought air pollutant effects on childhood asthma or bronchitic symptoms would be a major pathway by which childhood air pollution exposure affects adult respiratory health."

Google DeepMind's AI Systems Can Now Solve Complex Math Problems (technologyreview.com) 40

Google DeepMind has announced that its AI systems, AlphaProof and AlphaGeometry 2, have achieved silver medal performance at the 2024 International Mathematical Olympiad (IMO), solving four out of six problems and scoring 28 out of 42 possible points in a significant breakthrough for AI in mathematical reasoning. This marks the first time an AI system has reached such a high level of performance in this prestigious competition, which has long been considered a benchmark for advanced mathematical reasoning capabilities in machine learning.

AlphaProof, a system that combines a pre-trained language model with reinforcement learning techniques, demonstrated its new capability by solving two algebra problems and one number theory problem, including the competition's most challenging question. Meanwhile, AlphaGeometry 2 successfully tackled a complex geometry problem, Google wrote in a blog post. The systems' solutions were formally verified and scored by prominent mathematicians, including Fields Medal winner Prof Sir Timothy Gowers and IMO Problem Selection Committee Chair Dr Joseph Myers, lending credibility to the achievement.

The development of these AI systems represents a significant step forward in bridging the gap between natural language processing and formal mathematical reasoning, the company argued. By fine-tuning a version of Google's Gemini model to translate natural language problem statements into formal mathematical language, the researchers created a vast library of formalized problems, enabling AlphaProof to train on millions of mathematical challenges across various difficulty levels and topic areas. While the systems' performance is impressive, challenges remain, particularly in the field of combinatorics where both AI models were unable to solve the given problems. Researchers at Google DeepMind continue to investigate these limitations, the company said, aiming to further improve the systems' capabilities across all areas of mathematics.

Proposed NASA Budget Cuts Would End Chandra X-Ray Observatory (spacenews.com) 81

A NASA committee determined that the Chandra X-ray Observatory would have to cease operations under the proposed budget cuts in NASA's 2025 budget. The committee reviewed various options but found that only shutting down Chandra fit within the proposed budget, although alternatives could keep the observatory running with limited capabilities. SpaceNews reports: NASA established the Operations Paradigm Change Review (OPCR) committee this spring to look at ways of reducing the costs of operating Chandra and the Hubble Space Telescope as part of broader efforts to deal with a billion-dollar shortfall in agency science funding. The fiscal year 2025 budget proposal included a 40% cut in Chandra's budget, with further reductions through 2029, while cutting Hubble's budget by 10% in 2025. Astronomers strongly opposed the proposed cuts, particularly for Chandra. They argued that the reductions would effectively shut down the telescope, a conclusion backed by Patrick Slane, director of the Chandra X-Ray Center, in an open letter shortly after the release of the budget proposal.

The OPCR concurred. "The committee agreed that the continuation of a scientifically viable Chandra mission is not possible within the funding guidance," said Rob Kennicutt, an astronomer from the University of Arizona and Texas A&M University who served on the review committee, in a July 23 presentation at a meeting of the Astrophysics Advisory Committee, or APAC. "This is a serious threat to the observatory." Shutting down Chandra was one of four options presented to the OPCR by the Chandra team and the only one, he said, that fit within NASA's proposed budget profile. Three others would keep Chandra going with reduced capabilities and with budgets higher than what NASA proposed but below current levels. "We think it's possible to run Chandra for less money" than today, he said, "but more than what they were given."

Russia Announces It Will Create Core of New Space Station By 2030 (reuters.com) 99

"Despite its domestic space program faltering even before sanctions due to its invasion of Ukraine, and at least one very public failure on a less ambitious project, Russia has announced it will begin construction of a Russian-only replacement for the ISS and place it in a more difficult-to-access polar orbit," writes longtime Slashdot reader Baron_Yam. "Russia is motivated by military and political demands to achieve this, but whether it has the means or not seems uncertain at best." Reuters reports: Russia is aiming to create the four-module core of its planned new orbital space station by 2030, its Roscosmos space agency said on Tuesday. The head of Roscosmos, Yuri Borisov, signed off on the timetable with the directors of 19 enterprises involved in creating the new station. The agency confirmed plans to launch an initial scientific and energy module in 2027. It said three more modules would be added by 2030 and a further two between 2031 and 2033. [...]

Apart from the design and manufacture of the modules, Roscomos said the schedule approved by Borisov includes flight-testing a new-generation crewed spacecraft and building rockets and ground-based infrastructure. The new station will enable Russia to "solve problems of scientific and technological development, national economy and national security that are not available on the Russian segment of the ISS due to technological limitations and the terms of international agreements," it said.

Australian Scientists Genetically Engineer Common Fly Species To Eat More of Humanity's Waste (theguardian.com) 56

An anonymous reader quotes a report from The Guardian: A team of Australian scientists is genetically engineering a common fly species so that it can eat more of humanity's organic waste while producing ingredients for making everything from lubricants and biofuels to high-grade animal feeds. Black soldier flies are already being used commercially to consume organic waste, including food waste, but tweaking their genetics could widen the range of waste their larvae consume while, in the process, producing fatty compounds and enzymes. In a scientific paper, the team based at Sydney's Macquarie University outlined their hopes for the flies and how they could also cut the amount of planet-warming methane produced when organic waste breaks down.

"We are heading towards a climate disaster, and landfill waste releases methane. We need to get that to zero," Dr Kate Tepper, a lead author of the paper, said. Dr Maciej Maselko runs an animal synthetic biology lab at Macquarie University where Tepper has already started engineering the flies. Maselko said insects would be the "next frontier" in dealing with the planet's waste management problem, which weighs in at about 1 billion tons a year in food waste alone. Black soldier flies are found in all continents except Antarctica. "If you've got a compost bin, then you've probably got some," Maselko said. The fly larvae can eat double their body weight a day and, like other insects, their larvae are used for animal feed. Maselko said the flies could already do the job of consuming waste faster than microbes. The university team has created a spin-off company, EntoZyme, to commercialize their work and hopes to have the first genetically engineered flies for use in waste facilities by the end of the year. [...]

Creating a suite of genetically engineered flies would see them also produce enzymes used in animal feeds, textiles and pharmaceuticals, and fatty compounds that can be used to make biofuels and lubricants. Another proposed use is for some flies to be able to consume contaminated waste, which would then leave behind their poo that could be used as fertilizer. Tepper said flies can be engineered to deal with pollutants in several ways, including by breaking pollutants down into less toxic or inorganic compounds, evaporating them into the air or accumulating some pollutants into their bodies that can then be separated, leaving clean organic waste behind.
The research has been published in the journal Communications Biology.

Physics Pioneer Receives PhD After 75 Years For Discovering Kaon Particle (theguardian.com) 63

Rosemary Fowler, a pioneering physicist who discovered the kaon particle during her doctoral research in 1948, has been awarded an honorary doctorate from the University of Bristol -- 75 years after she left her PhD to raise a family. The Guardian reports: Rosemary Fowler, 98, discovered the kaon particle during her doctoral research under Cecil Powell at the University of Bristol in 1948, which contributed to his Nobel prize for physics in 1950. Fowler's discovery helped lead to a revolution in the theory of particle physics, and it continues to be proven correct -- predicting particles such as the Higgs boson, discovered at Cern in Geneva, Switzerland. But she left university without completing her PhD to marry fellow physicist Peter Fowler in 1949, a decision she later described as pragmatic after she went on to have three children in a time of postwar food rationing.

At 22, Fowler spotted something when viewing unusual particle tracks -- a particle that decayed into three pions, a type of subatomic particle. She said: "I knew at once that it was new and would be very important. We were seeing things that hadn't been seen before -- that's what research in particle physics was. It was very exciting." The track, later labelled K, was evidence of an unknown particle, now known as the kaon or K meson. The K track was the mirror image of a particle seen before by colleagues in Manchester, but their track decayed into two pions, not three. Trying to understand how these images were the same, yet behaved differently, helped lead to a revolution in the theory of particle physics. The year after the discovery, Fowler left university having published her discovery in three academic papers.

Mystery Oxygen Source Discovered on the Sea Floor 48

Something is pumping out large amounts of oxygen at the bottom of the Pacific Ocean, at depths where a total lack of sunlight makes photosynthesis impossible. Nature: The phenomenon was discovered in a region strewn with ancient, plum-sized formations called polymetallic nodules, which could play a part in the oxygen production by catalysing the splitting of water molecules, researchers suspect. The findings are published in Nature Geoscience. "We have another source of oxygen on the planet, other than photosynthesis," says study co-author Andrew Sweetman, a sea-floor ecologist at the Scottish Association for Marine Science in Oban, UK -- although the mechanism behind this oxygen production remains a mystery. The findings could also have implications for understanding how life began, he says, as well as for the possible impact of deep-sea mining in the region.

The observation is "fascinating," says Donald Canfield, a biogeochemist at the University of Southern Denmark in Odense. "But I find it frustrating, because it raises a lot of questions and not very many answers." Sweetman and his collaborators first noticed something amiss during field work in 2013. The researchers were studying sea-floor ecosystems in the Clarion-Clipperton Zone, an area between Hawaii and Mexico that is larger than India and a potential target for the mining of metal-rich nodules. During such expeditions, the team releases a module that sinks to the sea floor to perform automated experiments. Once there, the module drives cylindrical chambers down to close off small sections of the sea floor -- together with some seawater -- and create "an enclosed microcosm of the seafloor," the authors write. The lander then measures how the concentration of oxygen in the confined seawater changes over periods of up to several days.

Without any photosynthetic organisms releasing oxygen into the water, and with any other organisms consuming the gas, oxygen concentrations inside the chambers should slowly fall. Sweetman has seen that happen in studies he has conducted in areas of the Southern, Arctic and Indian oceans, and in the Atlantic. Around the world, sea-floor ecosystems owe their existence to oxygen carried by currents from the surface, and would quickly die if cut off. (Most of that oxygen originates in the North Atlantic and is carried to deep oceans around the world by a 'global conveyor belt.')

US Wins Math Olympiad For First Time In 21 Years (npr.org) 60

The United States has claimed victory at the International Mathematical Olympiad in Chiang Mai, Thailand, marking its first win in over two decades. The competition, which pitted top-ranked high school math students from more than 100 countries against each other, saw the U.S. team emerge triumphant after two days of intense problem-solving. NPR adds: The U.S. team last won the Olympiad in 1994. Reports in recent years have raised concerns that American math students are falling behind those in the rest of the world. But, Po-Shen Loh, a professor at Carnegie Mellon University and head coach for Team USA, says, "At least in this case with the Olympiads, we've been able to prove that our top Americans are certainly at the level of the top people from the other countries."

US Prepares Jamming Devices Targeting Russia, China Satellites (msn.com) 45

In April the U.S. Space Force began testing "a new ground-based satellite jamming weapon to help keep U.S. military personnel safe from potential 'space-enabled' attacks" (according to a report from Space.com). The weapon was "designed to deny, degrade, or disrupt communications with satellites overhead, typically through overloading specific portions of the electromagnetic spectrum with interference," according to the article, with the miitary describing it as a small form-factor system "designed to be fielded in large numbers at low-cost and operated remotely" and "provide counterspace electronic warfare capability to all of the new Space Force components globally."

And now, Bloomberg reports that the U.S. is about to deploy them: The devices aren't meant to protect U.S. satellites from Chinese or Russian jamming but "to responsibly counter adversary satellite communications capabilities that enable attacks," the Space Force said in a statement to Bloomberg News. The Pentagon strives — on the rare occasions when it discusses such space capabilities — to distinguish its emerging satellite-jamming technology as purely defensive and narrowly focused. That's as opposed to a nuclear weapon the U.S. says Russia is developing that could create high-altitude electromagnetic pulses that would take out satellites and disrupt entire communications networks.

The first 11 of 24 Remote Modular Terminal jammers will be deployed in several months, and all of them could be in place by Dec. 31 at undisclosed locations, according to the Space Force statement... The new terminals augment a much larger jamming weapon called the Counter Communications System that's already deployed and a mid-sized one called Meadowlands "by providing the ability to have a proliferated, remotely controlled and relatively relocatable capability," the Space Force said. The Meadowlands system has encountered technical challenges that have delayed its delivery until at least October, about two years later than planned.

China has "hundreds and hundreds of satellites on orbit designed to find, fix, track, target and yes, potentially engage, US and allied forces across the Indo-Pacific," General Stephen Whiting, head of US Space Command, said Wednesday at the annual Aspen Security Forum. "So we've got to understand that and know what it means for our forces."

Bloomberg also got this comment from the chief director of space security and stability at the Secure World Foundation (which produces reports on counterspace weapons). The new U.S. Space Force jamming weapons are "reversible, temporary, non-escalatory and allow for plausible deniability in terms of who the instigator is."

After 12 Years, Mars Rover Curiosity Makes 'Most Unusual Find to Date' (cnn.com) 37

12 years on Mars — and NASA's Curiosity rover "has made its most unusual find to date," reports CNN — rocks made of pure sulfur.

"And it all began when the 1-ton rover happened to drive over a rock and crack it open, revealing yellowish-green crystals never spotted before on the red planet." "I think it's the strangest find of the whole mission and the most unexpected," said Ashwin Vasavada, Curiosity project scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. "I have to say, there's a lot of luck involved here. Not every rock has something interesting inside...." White stones had been visible in the distance, and the mission scientists wanted a closer look. The rover drivers at JPL, who send instructions to Curiosity, did a 90-degree turn to put the robotic explorer in the right position for its cameras to capture a mosaic of the surrounding landscape. On the morning of May 30, Vasavada and his team looked at Curiosity's mosaic and saw a crushed rock lying amid the rover's wheel tracks. A closer picture of the rock made clear the "mind-blowing" find, he said...

"No one had pure sulfur on their bingo card," Vasavada said...

Members of the team were stunned twice — once when they saw the "gorgeous texture and color inside" the rock and then when they used Curiosity's instruments to analyze the rock and received data indicating it was pure sulfur, Vasavada said.

Vasavada also was grateful for the original landing site where Curiosity began methodically exploring back in 2012.

"I'm glad we chose something that was 12 years' worth of science."

'Smart Soil' Grows 138% Bigger Crops Using 40% Less Water (newatlas.com) 69

Scientists at the University of Texas at Austin have developed a "smart soil" that can keep plants better hydrated and provide a controlled release of nutrients. As reported by New Atlas, tests found that it "drastically improved crop growth while using far less water." From the report: The soil gets its "smart" moniker thanks to the addition of a specially formulated hydrogel, which works to absorb more water vapor from the air overnight, then releasing it to the plants' roots during the day. Incorporating calcium chloride into the hydrogel also provides a slow release of this vital nutrient. The team tested the new smart soil in lab experiments, growing plants in 10 grams of soil, with some including 0.1 g of hydrogel. A day/night cycle was simulated, with 12 hours of darkness at 25 C (77 F) and either 60% or 90% relative humidity, followed by 12 hours of simulated sunlight at 35 C (95 F) and 30% humidity.

Sure enough, plants growing in the hydrogel soil showed a 138% boost to their stem length, compared to the control group. Importantly, the hydrogel-grown plants achieved this even while requiring 40% less direct watering. In future work, the team plans to try incorporating other types of fertilizers, and conducting longer field experiments.
The research was published in the journal ACS Materials Letters.

May Solar Superstorm Caused Largest 'Mass Migration' of Satellites In History (space.com) 16

A solar superstorm in May caused thousands of satellites to simultaneously maneuver to maintain altitude due to the thickening of the upper atmosphere, creating potential collision hazards as existing prediction systems struggled to cope. Space.com reports: According to a pre-print paper published on the online repository arXiv on June 12, satellites and space debris objects in low Earth orbit -- the region of space up to an altitude of 1,200 miles (2,000 kilometers) -- were sinking toward the planet at the speed of 590 feet (180 meters) per day during the four-day storm. To make up for the loss of altitude, thousands of spacecraft began firing their thrusters at the same time to climb back up. That mass movement, the authors of the paper point out, could have led to dangerous situations because collision avoidance systems didn't have time to calculate the satellites' changing paths.

The solar storm that battered Earth from May 7 to 10 reached the intensity of G5, the highest level on the five-step scale used by the National Oceanic and Atmospheric Administration (NOAA) to assess the strength of solar storms. It was the strongest solar storm to hit Earth since 2003. The authors of the paper, however, pointed out that the environment around the planet has changed profoundly since that time. While only a few hundred satellites were orbiting Earth twenty years ago, there are thousands today. The authors of the paper put the number of "active payloads at [low Earth orbit]" at 10,000. [...] The new paper points out that space weather forecasts ahead of the May storm failed to accurately predict the duration and intensity of the event, making satellite collision predictions nearly impossible.

On the upside, the storm helped to clear out some junk as defunct satellites and debris fragments spiraled deeper into the atmosphere. The authors of the report estimate that thousands of space debris objects lost several kilometers in altitude during the storm. More powerful solar storms can be expected in the coming months as the peak of the current solar cycle -- the 11-year ebb and flow in the number of sunspots, solar flares and eruptions -- is expected in late 2024 and early 2025.

NASA's Curiosity Rover Discovers Yellow Sulfur Crystals In Martian Rock (phys.org) 25

NASA reports in an article for Phys.Org: Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals. Since October 2023, the rover has been exploring a region of Mars rich with sulfates, a kind of salt that contains sulfur and forms as water evaporates. But where past detections have been of sulfur-based minerals -- in other words, a mix of sulfur and other materials -- the rock Curiosity recently cracked open is made of elemental (pure) sulfur. It isn't clear what relationship, if any, the elemental sulfur has to other sulfur-based minerals in the area.

While people associate sulfur with the odor from rotten eggs (the result of hydrogen sulfide gas), elemental sulfur is odorless. It forms in only a narrow range of conditions that scientists haven't associated with the history of this location. And Curiosity found a lot of it -- an entire field of bright rocks that look similar to the one the rover crushed. "Finding a field of stones made of pure sulfur is like finding an oasis in the desert," said Curiosity's project scientist, Ashwin Vasavada of NASA's Jet Propulsion Laboratory in Southern California. "It shouldn't be there, so now we have to explain it. Discovering strange and unexpected things is what makes planetary exploration so exciting."

NASA Ends VIPER Project (nasa.gov) 30

Following a comprehensive internal review, NASA announced Wednesday its intent to discontinue development of its VIPER (Volatiles Investigating Polar Exploration Rover) project. NASA: NASA stated cost increases, delays to the launch date, and the risks of future cost growth as the reasons to stand down on the mission. The rover was originally planned to launch in late 2023, but in 2022, NASA requested a launch delay to late 2024 to provide more time for preflight testing of the Astrobotic lander. Since that time, additional schedule and supply chain delays pushed VIPER's readiness date to September 2025, and independently its CLPS (Commercial Lunar Payload Services) launch aboard Astrobotic's Griffin lander also has been delayed to a similar time. Continuation of VIPER would result in an increased cost that threatens cancellation or disruption to other CLPS missions. NASA has notified Congress of the agency's intent.

'Supermodel Granny' Drug Extends Life In Mice By 25%, Study Finds 95

A drug has been shown to extend the lifespan of laboratory mice by nearly 25%, with treated mice displaying fewer cancers and improved health and strength. It earned them the nickname "supermodel grannies" due to their youthful appearance. "The drug is already being tested in people, but whether it would have the same anti-ageing effect is unknown," reports the BBC. From the report: The team at the MRC Laboratory of Medical Science, Imperial College London and Duke-NUS Medical School in Singapore were investigating a protein called interleukin-11. Levels of it increase in the human body as we get older, it contributes to higher levels of inflammation, and the researchers say it flips several biological switches that control the pace of ageing.

The researchers performed two experiments. The first genetically engineered mice so they were unable to produce interleukin-11. The second waited until mice were 75 weeks old (roughly equivalent to a 55-year-old person) and then regularly gave them a drug to purge interleukin-11 from their bodies. The results, published in the journal Nature, showed lifespans were increased by 20-25% depending on the experiment and sex of the mice.

Old laboratory mice often die from cancer, however, the mice lacking interleukin-11 had far lower levels of the disease. And they showed improved muscle function, were leaner, had healthier fur and scored better on many measures of frailty.

Signs of Two Gases In Clouds of Venus Could Indicate Life, Scientists Say (theguardian.com) 39

Astronomers say they've detected two gases that could indicate the presence of life forms lurking in the clouds of Venus. The Guardian reports: Findings presented at the national astronomy meeting in Hull on Wednesday bolster evidence for a pungent gas, phosphine, whose presence on Venus has been fiercely disputed. A separate team revealed the tentative detection of ammonia, which on Earth is primarily produced by biological activity and industrial processes, and whose presence on Venus scientists said could not readily be explained by known atmospheric or geological phenomena. "It could be that if Venus went through a warm, wet phase in the past then as runaway global warming took effect [life] would have evolved to survive in the only niche left to it -- the clouds," said Dr Dave Clements, a reader in astrophysics at Imperial College London, told the meeting. "Our findings suggest that when the atmosphere is bathed in sunlight the phosphine is destroyed," Clements said. "All that we can say is that phosphine is there. We don't know what's producing it. It may be chemistry that we don't understand. Or possibly life."

In a second talk, Prof Jane Greaves, an astronomer at Cardiff University, presented preliminary observations from the Green Bank telescope indicating ammonia, which on Earth is made through either industrial processes or by nitrogen-converting bacteria. Greaves said: "Even if we confirmed both of these [findings], it is not evidence that we have found these magic microbes and they're living there today," adding that there were not yet "any ground truths."
Dr Robert Massey, the deputy executive director at the Royal Astronomical Society, said in a statement: "These are very exciting findings but it must be stressed that the results are only preliminary and more work is needed to learn more about the presence of these two potential biomarkers in Venus's clouds. Nevertheless, it is fascinating to think that these detections could point to either possible signs of life or some unknown chemical processes. It will be interesting to see what further investigations unearth over the coming months and years."

Psilocybin Desynchronizes the Human Brain (nytimes.com) 80

An anonymous reader quotes a report from the New York Times: The image, as it happens, comes from dozens of brain scans produced by researchers at Washington University School of Medicine in St. Louis who gave psilocybin, the compound in "magic mushrooms," to participants in a study before sending them into a functional M.R.I. scanner. The kaleidoscopic whirl of colors they recorded is essentially a heat map of brain changes, with the red, orange and yellow hues reflecting a significant departure from normal activity patterns. The blues and greens reflect normal brain activity that occurs in the so-called functional networks, the neural communication pathways that connect different regions of the brain.

The scans, published Wednesday in the journal Nature, offer a rare glimpse into the wild neural storm associated with mind-altering drugs. Researchers say they could provide a potential road map for understanding how psychedelic compounds like psilocybin, LSD and MDMA can lead to lasting relief from depression, anxiety and other mental health disorders. "Psilocybin, in contrast to any other drug we've tested, has this massive effect on the whole brain that was pretty unexpected," said Dr. Nico Dosenbach, a professor of neurology at Washington University and a senior author of the study. "It was quite shocking when we saw the effect size."
Brian Mathur, a systems neuroscientist at the University of Maryland School of Medicine in Baltimore, says these findings cannot show exactly what causes the therapeutic benefit of psilocybin, but "it's possible psilocybin is directly causing" the brain-network changes. That, or it is creating a psychedelic experience that in turn causes parts of the brain to behave differently.

The next step is to determine whether psilocybin's blood-flow changes in the brain or its direct effects on neurons, or both, are responsible for the brain-network disruptions. "The best part of this work is that it's going to provide a means forward for the field to develop further hypotheses that can and should be tested," Mathur says.

Meta Opens Pilot Program For Researchers To Study Instagram's Impact On Teen Mental Health (theatlantic.com) 13

An anonymous reader quotes a report from The Atlantic: Now, after years of contentious relationships with academic researchers, Meta is opening a small pilot program that would allow a handful of them to access Instagram data for up to about six months in order to study the app's effect on the well-being of teens and young adults. The company will announce today that it is seeking proposals that focus on certain research areas -- investigating whether social-media use is associated with different effects in different regions of the world, for example -- and that it plans to accept up to seven submissions. Once approved, researchers will be able to access relevant data from study participants -- how many accounts they follow, for example, or how much they use Instagram and when. Meta has said that certain types of data will be off-limits, such as user-demographic information and the content of media published by users; a full list of eligible data is forthcoming, and it is as yet unclear whether internal information related to ads that are served to users or Instagram's content-sorting algorithm, for example, might be provided. The program is being run in partnership with the Center for Open Science, or COS, a nonprofit. Researchers, not Meta, will be responsible for recruiting the teens, and will be required to get parental consent and take privacy precautions.

UK First European Country To Approve Lab-grown Meat, Starting With Pet Food (theguardian.com) 43

Lab-grown pet food is to hit UK shelves as Britain becomes the first country in Europe to approve cultivated meat. From a report: The Animal and Plant Health Agency and the Department for Environment, Food and Rural Affairs have approved the product from the company Meatly. It is thought there will be demand for cultivated pet food, as animal lovers face a dilemma about feeding their pets meat from slaughtered livestock.

Research suggests the pet food industry has a climate impact similar to that of the Philippines, the 13th most populous country in the world. A study by the University of Winchester found that 50% of surveyed pet owners would feed their pets cultivated meat, while 32% would eat it themselves. The Meatly product is cultivated chicken. It is made by taking a small sample from a chicken egg, cultivating it with vitamins and amino acids in a lab, then growing cells in a container similar to those in which beer is fermented. The result is a pate-like paste.

Startups Are Building Balloons To Hoist Tourists Into the Stratosphere (cnbc.com) 66

An anonymous reader quotes a report from CNBC: CNBC spoke to three startups -- France-based Zephalto, Florida-based Space Perspective and Arizona-based World View -- that aim to hoist tourists to the stratosphere using pressurized capsules and massive gas-filled balloons. "The capsule itself is designed to to carry eight customers and two crew into the stratosphere," said Ryan Hartman, CEO of World View. "There will be a center bar where people can gather, and then, of course, there will be a bathroom aboard the capsule." The balloon rides will last around 6 hours, but will not take passengers all the way to space. Most will reach heights of 15 to 19 miles above the earth's surface, flying in an area known as the stratosphere. The start of space is generally accepted by the U.S. government to be around 80 kilometers, or about 50 miles, above the earth's surface.

Jane Poynter, founder and co-CEO of Space Perspective, has a differing view. "There is no universal definition of space," Poynter said. "We are regulated as a spaceship. If we go over 98,000 feet, we are a spaceship. Outside the capsule, it's essentially a vacuum. We're above 99% of Earth's atmosphere, which is why the sky is so deep black." Compared to rocket-powered space tourism, the physical sensation that passengers will experience on a stratospheric balloon ride is more comparable to being on an airplane. Passengers will not experience weightlessness. "We don't need any physical requirements to board the balloon," said Vincent Farret d'Asties, the founder and chief pilot at Zephalto. "If you can board a standard plane, you can board the balloon."

All three companies told CNBC that they were pleased with consumer interest. World Views says it sold 1,250 tickets so far while Space Perspective has sold 1,800. Zephalto did not tell CNBC how many tickets it sold, but said its initial flights were fully booked. Ticket prices range from $50,000 per seat with World View to around $184,000 with Zephalto. Space Perspective sells tickets to its experience for $125,000 per seat. That's all assuming commercial service gets off the ground. Only Zephalto has performed crewed tests so far, though not at the company's target altitude of about 15 miles above the earth's surface.

'Amazing' New Technology Set To Transform the Search For Alien Life (theguardian.com) 127

Robin McKie writes via The Guardian: Scientists with Breakthrough Listen, the world's largest scientific research program dedicated to finding alien civilizations, say a host of technological developments are about to transform the search for intelligent life in the cosmos. These innovations will be outlined at the group's annual conference, which is to be held in the UK for the first time, in Oxford, this week. Several hundred scientists, from astronomers to zoologists, are expected to attend. "There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI," said astronomer Steve Croft, a project scientist with Breakthrough Listen. "They are going to transform how we look for alien civilizations."

Among these new instruments are the Square Kilometer Array, made up of hundreds of radio telescopes now being built in South Africa and Australia, and the Vera Rubin Observatory that is being constructed in Chile. The former will become the world's most powerful radio astronomy facility while the latter, the world's largest camera, will be able to image the entire visible sky every three or four nights, and is expected to help discover millions of new galaxies and stars. Both facilities are set to start observations in the next few years and both will provide data for Breakthrough Listen. Using AI to analyze these vast streams of information for subtle patterns that would reveal evidence of intelligent life will give added power to the search for alien civilizations, added Croft.

"Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters -- things like that." [...] Croft remains optimistic that we will soon succeed in making contact. "We know that the conditions for life are everywhere, we know that the ingredients for life are everywhere. I think it would be deeply weird if it turned out we were the only inhabited planet in the galaxy or in the universe. But you know, it's possible."

Startup Makes Butter Using CO2 and Water (newatlas.com) 206

A Californian startup funded by Bill Gates is making rich, fatty "butter" using just carbon dioxide and hydrogen, with other dairy-free alternatives in the works. New Atlas reports: The San Jose company, Savor, uses a thermochemical process to create its animal-like fat, which is free of the environmental footprint of both the dairy industry and plant-based alternatives. "They started with the fact that all fats are made of varying chains of carbon and hydrogen atoms," Gates wrote in a blog post. "Then they set out to make those same carbon and hydrogen chains -- without involving animals or plants. They ultimately developed a process that involves taking carbon dioxide from the air and hydrogen from water, heating them up, and oxidizing them to trigger the separation of fatty acids and then the formulation of fat."

"The idea of switching to lab-made fats and oils may seem strange at first," Gates wrote. "But their potential to significantly reduce our carbon footprint is immense. By harnessing proven technologies and processes, we get one step closer to achieving our climate goals." Savor's 'butter' is easily produced and scalable, but convincing people to swap out butter and other dairy products for 'experimental' foods will remain a challenge for the foreseeable future. Gates is hoping, however, that his support will do more than start a conversation. "The process doesn't release any greenhouse gases, and it uses no farmland and less than a thousandth of the water that traditional agriculture does," he added. "And most important, it tastes really good -- like the real thing, because chemically it is."
The research has been published in the journal Nature Sustainability.

NASA Transmits Hip-Hop Song To Deep Space for First Time (nasa.gov) 89

NASA: The stars above and on Earth aligned as an inspirational message and lyrics from the song "The Rain (Supa Dupa Fly)" by hip-hop artist Missy Elliott were beamed to Venus via NASA's DSN (Deep Space Network). The agency's Jet Propulsion Laboratory in Southern California sent the transmission at 10:05 a.m. PDT on Friday, July 12. As the largest and most sensitive telecommunication service of NASA's Space Communications and Navigation (SCaN) program, the DSN has an array of giant radio antennas that allow missions to track, send commands, and receive scientific data from spacecraft venturing to the Moon and beyond. To date, the system has transmitted only one other song into space, making the transmission of Elliott's song a first for hip-hop and NASA.

"Both space exploration and Missy Elliott's art have been about pushing boundaries," said Brittany Brown, director, Digital and Technology Division, Office of Communications at NASA Headquarters in Washington, who initially pitched ideas to Missy's team to collaborate with the agency. "Missy has a track record of infusing space-centric storytelling and futuristic visuals in her music videos, so the opportunity to collaborate on something out of this world is truly fitting." The song traveled about 158 million miles (254 million kilometers) from Earth to Venus -- the artist's favorite planet. Transmitted at the speed of light, the radio frequency signal took nearly 14 minutes to reach the planet. The transmission was made by the 34-meter (112-foot) wide Deep Space Station 13 (DSS-13) radio dish antenna, located at the DSN's Goldstone Deep Space Communications Complex, near Barstow in California. Coincidentally, the DSS-13 also is nicknamed Venus.

Radar Images Suggest There's a Tunnel On the Moon (gizmodo.com) 58

Longtime Slashdot reader fahrbot-bot shares a report from Gizmodo: A team of researchers think they've discovered a cave on the Moon in radar images of the lunar surface, which they posit could be a future site for an established human presence on our rocky satellite. The tunnel is in the Mare Tranquillitatis (Sea of Tranquility) pit, the deepest known pit on the Moon. (If the name is familiar to you, the Sea of Tranquility is where the Apollo 11 mission landed in 1969.) The pit formed due to a lava tube's roof collapse or a collapse of a void structure created by tectonic processes. To look for potential cave structures within the pit, the researchers studied side-looking radar images taken by the Lunar Reconnaissance Orbiter's Mini-RF instrument between 2009 and 2011. The team then conducted 3D radar simulations of potential geometries of the pit and its cave, to determine that the brightness they saw in radar images could be due to subsurface features. Ultimately, the team determined there is a tunnel in the pit that is between 98 feet (30 meters) long and 262ft (80m) long. The tunnel is roughly 148ft (45m) wide and is either flat or inclined with a maximum steepness of 45 degrees. "The exploration of lunar caves through future robotic missions could provide a fresh perspective on the lunar subsurface and yield new insights into the evolution of lunar volcanism," the team wrote in the paper. "Furthermore, direct exploration could confirm the presence of stable subsurface environments shielded from radiation and with optimal temperature conditions for future human utilization."

The findings have been published in the journal Nature Astronomy.

Scientists Discover How Pancreatic Cancer Switches Off a 'Tumor Suppressor' Gene (theguardian.com) 25

An anonymous reader shared this report from the Guardian: A team of researchers from the UK and US have found that pancreatic cancer is able to shut down molecules in one of the body's most important genes, helping the disease to grow and spread rapidly... Dr Maria Hatziapostolou, of Nottingham Trent University's John van Geest Cancer Research Centre, said: "This work, which has provided new understanding and knowledge of how the cancer behaves, will hopefully help pave the way for potential new treatments in the future...."

For the study, published in the journal Gastro Hep Advances, the researchers analysed healthy as well as pancreatic cancer tissue samples. They found pancreatic cancers triggered a process known as DNA methylation, causing molecules in the normally beneficial HNF4A gene to switch off, allowing tumours to grow extremely quickly. The HNF4A gene is crucial to human health because it helps many of the body's organs to function properly. But the researchers discovered pancreatic cancer can covertly disable the gene's benefits. Hatziapostolou said: "Loss of HNF4A drives pancreatic cancer development and aggressiveness and we now know correlates with poor patient survival."

Scientists from the University of Nottingham, Stanford University and the University of California and Cedars-Sinai medical centre, Los Angeles, were also involved in the project.

The published study calls the targeted HNF4A gene is "a novel tumor suppressor in pancreatic cancer, regulating cancer growth and aggressiveness."

And ultimately, according to the Guardian, pancreatic cancer "is the 12th most common cancer worldwide," according to the Guardian, "with more than half a million people diagnosed every year. It has the worst survival rates of all the most common forms of the disease."

The researchers paper ends with this conclusion. "HNF4A silencing... drives pancreatic cancer development and aggressiveness leading to poor patient survival."

Virgin Galactic Flies 3D Printer Into Space. Its Next Mission: Bioprinting on the ISS (berkeley.edu) 13

"In a significant advancement for space technology, a team of UC Berkeley researchers, led by doctoral student Taylor Waddell, successfully launched a 3D printer into space," reports the university's student newspaper: As part of the Virgin Galactic 07 mission, the team sent a 3D printer named SpaceCAL to space to explore the potential of Computed Axial Lithography, or CAL, and additive manufacturing in space... During its 140-second flight in suborbital space, the SpaceCAL printer autonomously detected microgravity and printed four test parts: two space shuttles and two Benchies, or 3D-printed boats created to check the printer's accuracy, according to Sean Chu, a member of the team who worked on designing structures and mechanisms. Within the 140 seconds, the process involved multiple steps such as printing, post-washing, flushing with water and post-curing with light to fully solidify the parts.
But that's just the beginning, says the university's engineering department: To date, CAL has shown that it can successfully print with more than 60 different materials on Earth, such as silicones, glass composites and biomaterials. According to Waddell, this versatility could come in handy for both the cabin and the crew... "CAL is also capable of repairing the crew. We can print dental replacements, skin grafts or lenses, or things personalized in emergency medicine for astronauts, which is very important in these missions, too."

Someday, CAL may be used to print even more sophisticated parts, such as human organs. Lawrence Livermore National Lab has received a grant from NASA to test this technology on the International Space Station. "They're going to basically do bioprinting on the Space Station," said Waddell. "And the long, long-term goal is to print organs up in space with CAL, then bring them back down to Earth." Next, Waddell and his colleagues hope to begin work with NASA on developing and validating a single object that could support crew health and wellness, like a dental crown for an astronaut or a surgical wound closure tool...

This project was made possible through a $1.4 million grant and engineering support provided by NASA. In addition, Virgin Galactic played a pivotal role in taking this project to the next level.

Fastest Object Ever Made By Humans Continues Circling the Sun, 500x Faster Than Sound (sciencealert.com) 61

An anonymous reader shared this report from ScienceAlert: NASA's Parker Solar Probe, tasked with taking a close-up look at the Sun's outer corona, has just equalled the record for the fastest-moving human-made object ever. The previous record holder? The Parker Solar Probe, again. The probe was recorded traveling at 635,266 kilometers (394,736 miles) per hour on June 29, the second time it's reached that speed since it launched in 2018. We're talking around 500 times faster than the speed of sound here. It's on course to get even faster too, with a top speed of around 692,000 kph (430,000 mph) expected when it makes its closest approach to the Sun in 2025.
It's the probe's 20th approach to the sun, according to the article, with the probe using Venus "to create a sort of gravity-powered slingshot," according to the article. (NASA has created a nice interactive 3D model of the probe...)

Besides collecting particle samples in 2021, "The probe is eventually going to get nice and close to the swirling mass of ultra-hot plasma surrounding the Sun, and take a wealth of different measurements to help improve our scientific understanding of it."

Joe Engle, the Last Living X-15 Pilot, Passed Away July 10 At the Age of 91 (nasa.gov) 10

clovis (Slashdot reader #4,684) writes: Joe Engle received his astronaut wings in a ceremony on July 15, 1965, for his flight in the hypersonic aircraft, reaching an altitude of 50 miles above the Earth. At 32, he was the youngest man to become an astronaut.

Later, he entered the Apollo program and eventually commanded the STS-2 flight of the Space Shuttle.

Here is an interview from 2004. I thought it was interesting that they used the F-104 as the chase plane and for training because the flight characteristics were so similar, which says a lot about the F-104.

Anyway, the X-15 project was a big deal for us science/geek types back when I was a kid. I wonder if it's something today's generation is even aware of.

NATO Countries Pledge $1 Billion To Strengthen Collection, Sharing of Space-Based Intel (defensescoop.com) 50

An anonymous reader quotes a report from DefenseScoop: A group of NATO countries are set to begin implementing a new project aimed at improving the alliance's ability to quickly share intelligence gathered by space-based assets operated by both member nations and the commercial sector. Seventeen NATO members signed a memorandum of understanding for the Alliance Persistence Surveillance from Space (APSS) program as part of the annual NATO summit being held in Washington this week, the alliance announced Tuesday. Members will now move into a five-year implementation phase of the project, during which allies will contribute more than $1 billion "to leverage commercial and national space assets, and to expand advanced exploitation capacities," according to a press release.

The United States is one of the nations signed onto the initiative, as well as Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, the Netherlands, Norway, Poland, Romania, Sweden and Turkey, according to a NATO source. The transatlantic organization created APSS last year with the intent to establish a "virtual constellation" -- dubbed Aquila -- comprising both national and commercial space systems, sensors and data that can be used by NATO's command structure and other allies. The project is considered "the largest multinational investment in space-based capabilities" in the alliance's history, and is set to increase NATO's ability "to monitor activities on the ground and at sea with unprecedented accuracy and timeliness," a press release stated.

Participating nations will be able to use their own space systems, provide tools for intelligence collection and analysis, or purchase space-based data gathered by commercial constellations. "Integrating and exploiting data from space effectively has been a growing challenge over time," a NATO press release stated. "By leveraging latest technologies from industry, APSS will help advance NATO's innovation agenda and offer a new platform to engage with the growing space industry." The APSS project is part of the larger implementation of NATO's overarching space policy adopted in 2019, which officially recognized space as a new operational domain. Since then, the alliance has worked to bolster its presence in space -- including the establishment of a NATO Space Centre in 2020 and approval of an official Space Branch within the Allied Command Transformation in June.

Dune-Inspired Spacesuit Recycles Urine Into Clean Drinking Water (phys.org) 58

Researchers from Cornell University have developed a novel urine collection and filtration system for spacesuits, designed to improve hygiene and comfort for astronauts during long spacewalks. This new system, inspired by the 'stillsuits' from the Dune franchise, recycles urine into potable water using a vacuum-based external catheter and a forward-reverse osmosis unit. It's expected to be tested for use in upcoming NASA moon and Mars missions. Phys.Org reports: [Researchers] have now designed a urine collection device, including an undergarment made of multiple layers of flexible fabric. This connects to a collection cup (with a different shape and size for women and men) of molded silicone, to fit around the genitalia. The inner face of the collection cup is lined with polyester microfiber or a nylon-spandex blend, to draw urine away from the body and towards the inner cup's inner face, from where it is sucked by a vacuum pump. A RFID tag, linked to an absorbent hydrogel, reacts to moisture by activating the pump.

Once collected, the urine is diverted to the urine filtration system, where it gets recycled with an efficiency of 87% through a two-step, integrated forward and reverse osmosis filtration system. This uses a concentration gradient to remove water from urine, plus a pump to separate water from salt. The purified water is then enriched in electrolytes and pumped into the in-suit drink bag, again available for consumption. Collecting and purifying 500ml of urine takes only five minutes.

The system, which integrates control pumps, sensors, and a liquid-crystal display screen, is powered by a 20.5V battery with a capacity of 40 amp-hours. Its total size is 38 by 23 by 23 cm, with a weight of approximately eight kilograms: sufficiently compact and light to be carried on the back of a spacesuit. Now that the prototype is available, the new design can be tested under simulated conditions, and subsequently during real spacewalks.
The design has been published in the journal Frontiers in Space Technology.

SpaceX's Historic Falcon 9 Success Streak Is Over (reuters.com) 46

An anonymous reader quotes a report from Reuters: SpaceX's workhorse Falcon 9 rocket was grounded by the U.S. Federal Aviation Administration (FAA) on Friday after one broke apart in space and doomed its payload of Starlink satellites, the first failure in more than seven years of a rocket relied upon by the global space industry. Roughly an hour after Falcon 9 lifted off from the Vandenberg Space Force Base in California on Thursday night, the rocket's second stage failed to reignite and deployed its 20 Starlink satellites on a shallow orbital path where they will soon reenter and burn up in Earth's atmosphere.

The attempt to reignite the engine "resulted in an engine RUD for reasons currently unknown," SpaceX CEO Elon Musk wrote early on Friday on his social media platform X, using an industry acronym for Rapid Unscheduled Disassembly that usually means explosion. The Falcon 9 will be grounded until SpaceX investigates the cause of the failure, fixes the rocket and receives the agency's approval, the FAA said in a statement. That process could take several weeks or months, depending on the complexity of the failure and SpaceX's plan to fix it. Musk said SpaceX was updating the software of the Starlink satellites to force their on-board thrusters to fire harder than usual to avoid a fiery atmospheric re-entry. "Unlike a Star Trek episode, this will probably not work, but it's worth a shot," Musk said.

The satellites' altitude is so shallow that Earth's gravity is pulling them 3 miles (5 km) closer toward the atmosphere with each orbit, SpaceX later said, confirming they would inevitably "re-enter Earth's atmosphere and fully demise." SpaceX said the second stage's failure occurred after engineers detected a leak of liquid oxygen, a propellant. The mishap occurred on Falcon 9's 354th mission. It was the first Falcon 9 failure since 2016, when a rocket exploded on a launch pad in Florida and destroyed its customer payload, an Israeli communications satellite.
The failure "breaks a success streak of more than 300 straight missions," notes Reuters.

"We knew this incredible run had to come to an end at some point," Tom Mueller, SpaceX's former vice president of propulsion who designed Falcon 9's engines. "... The team will fix the problem and start the cycle again."

Rivers Becoming 'Reservoirs of Disease' (bbc.com) 54

Scientists say "a reservoir of disease" is being created after discovering bacteria that naturally occur in rivers are becoming resistant to antibiotics due to the impact of sewage. From a report: Researchers at the University of Suffolk said bacterial strains found on the non-tidal section of the River Deben in Suffolk had acquired resistance by exchanging DNA with antibiotic resistant E. coli. Some bacteria have become resistant to the antibiotic carbapenem, which is used as the last line of defence in fighting infections already resistant to traditional antibiotics. Dr Nick Tucker, a microbiologist leading the research, described the discovery as "particularly worrying."

"Organisms that are currently low risk are being mixed with pathogenic organisms from sewage," he said. "We're needlessly adding pathogenic and virulence genes to bacteria found in the environment, and that could be creating a reservoir of disease." The team has been working closely with citizen scientists from the Deben Climate Centre, who have been taking water samples for two years. They have also been working with scientists at the government's CEFAS laboratories, who have helped identify the new strains that are being screened for their resistance to six of the most commonly-used antibiotics. The River Deben rises in Debenham, Suffolk, before flowing through Woodbridge and down to the North Sea.

When Scientific Citations Go Rogue (theconversation.com) 19

The Conversation: Reading and writing articles published in academic journals and presented at conferences is a central part of being a researcher. When researchers write a scholarly article, they must cite the work of peers to provide context, detail sources of inspiration and explain differences in approaches and results. A positive citation by other researchers is a key measure of visibility for a researcher's own work. But what happens when this citation system is manipulated? A recent Journal of the Association for Information Science and Technology article by our team of academic sleuths -- which includes information scientists, a computer scientist and a mathematician -- has revealed an insidious method to artificially inflate citation counts through metadata manipulations: sneaked references.

People are becoming more aware of scientific publications and how they work, including their potential flaws. Just last year more than 10,000 scientific articles were retracted. The issues around citation gaming and the harm it causes the scientific community, including damaging its credibility, are well documented. Citations of scientific work abide by a standardized referencing system: Each reference explicitly mentions at least the title, authors' names, publication year, journal or conference name, and page numbers of the cited publication. These details are stored as metadata, not visible in the article's text directly, but assigned to a digital object identifier, or DOI -- a unique identifier for each scientific publication.

References in a scientific publication allow authors to justify methodological choices or present the results of past studies, highlighting the iterative and collaborative nature of science. However, we found through a chance encounter that some unscrupulous actors have added extra references, invisible in the text but present in the articles' metadata, when they submitted the articles to scientific databases. The result? Citation counts for certain researchers or journals have skyrocketed, even though these references were not cited by the authors in their articles.

Pluto's Not Coming Back, But Astronomers Want To Redefine Planets Again (axios.com) 129

A group of astronomers want to change the definition of a planet. Their new proposed definition wouldn't bring Pluto back into the planetary fold, but it could reclassify thousands of celestial bodies across the universe. From a report: The International Astronomical Union's (IAU) current definition of a planet, established in 2006, includes only celestial bodies that are nearly round, are gravitationally dominant and orbit our Sun. This Sun-centric definition excludes all of the bodies we've discovered outside our solar system, even if they may fit all other parameters. They are instead considered exoplanets. Those behind the new proposal critiqued the IAU's definition in an upcoming paper in the Planetary Science Journal, arguing it's vague, not quantitative and unnecessarily exclusionary.

Their new proposal would instead classify planets based on their mass, considering a planet to be any celestial body that:
1. orbits one or more stars, brown dwarfs or stellar remnants and,
is more massive than 10ÂÂ kilograms (kg) and,
is less massive than 13 Jupiter masses (2.5 X 10^28Âkg).

Model Rocket Nails Vertical Landing After Three-Year Effort (hackaday.com) 81

Aryan Kapoor, a high schooler from JRD Propulsion, successfully developed a model rocket with SpaceX-style vertical landing capabilities. The three-year effort was made possible by a thrust-vector control and clever landing gear design. Hackaday reports: He started in 2021 with none of the basic skills needed to pull off something like this, but it seems like he quickly learned the ropes. His development program was comprehensive, with static test vehicles, a low-altitude hopper, and extensive testing of the key technology: thrust-vector control. His rocket uses two solid-propellant motors stacked on top of each other, one for ascent and one for descent and landing. They both live in a 3D printed gimbal mount with two servos that give the stack plus and minus seven degrees of thrust vectoring in two dimensions, which is controlled by a custom flight computer with a barometric altimeter and an inertial measurement unit. The landing gear is also clever, using rubber bands to absorb landing forces and syringes as dampers. You can watch the first successful test flight and landing on YouTube.

Night Owls' Cognitive Function 'Superior' To Early Risers, Study Suggests (theguardian.com) 85

The idea that night owls who don't go to bed until the early hours struggle to get anything done during the day may have to be revised. From a report: It turns out that staying up late could be good for our brain power as research suggests that people who identify as night owls could be sharper than those who go to bed early. Researchers led by academics at Imperial College London studied data from the UK Biobank study on more than 26,000 people who had completed intelligence, reasoning, reaction time and memory tests.

They then examined how participants' sleep duration, quality, and chronotype (which determines what time of day we feel most alert and productive) affected brain performance. They found that those who stay up late and those classed as "intermediate" had "superior cognitive function," while morning larks had the lowest scores. Going to bed late is strongly associated with creative types.

Researchers Discover a New Form of Scientific Fraud: Uncovering 'Sneaked References' (theconversation.com) 47

A recent study has exposed a method of artificially inflating citation counts through "sneaked references," which are extra citations included in metadata but not in the actual text of articles. This manipulation, uncovered in journals by Technoscience Academy, distorts citation metrics that are critical for research funding and academic promotions. The Conversation reports: The investigation began when Guillaume Cabanac, a professor at the University of Toulouse, wrote a post on PubPeer, a website dedicated to post-publication peer review, in which scientists discuss and analyze publications. In the post, he detailed how he had noticed an inconsistency: a Hindawi journal article that he suspected was fraudulent because it contained awkward phrases had far more citations than downloads, which is very unusual. The post caught the attention of several sleuths who are now the authors of the JASIST article. We used a scientific search engine to look for articles citing the initial article. Google Scholar found none, but Crossref and Dimensions did find references. The difference? Google Scholar is likely to mostly rely on the article's main text to extract the references appearing in the bibliography section, whereas Crossref and Dimensions use metadata provided by publishers.

To understand the extent of the manipulation, we examined three scientific journals that were published by the Technoscience Academy, the publisher responsible for the articles that contained questionable citations. [...] In the journals published by Technoscience Academy, at least 9% of recorded references were "sneaked references." These additional references were only in the metadata, distorting citation counts and giving certain authors an unfair advantage. Some legitimate references were also lost, meaning they were not present in the metadata. In addition, when analyzing the sneaked references, we found that they highly benefited some researchers. For example, a single researcher who was associated with Technoscience Academy benefited from more than 3,000 additional illegitimate citations. Some journals from the same publisher benefited from a couple hundred additional sneaked citations.

We wanted our results to be externally validated, so we posted our study as a preprint, informed both Crossref and Dimensions of our findings and gave them a link to the preprinted investigation. Dimensions acknowledged the illegitimate citations and confirmed that their database reflects Crossref's data. Crossref also confirmed the extra references in Retraction Watch and highlighted that this was the first time that it had been notified of such a problem in its database. The publisher, based on Crossref's investigation, has taken action to fix the problem.
To combat this practice of "sneaked references," the authors suggest several measures: rigorous verification of metadata by publishers and agencies like Crossref, independent audits to ensure data reliability, and increased transparency in managing references and citations.

Inside the Health Crisis of a Texas Bitcoin Town (time.com) 212

Longtime Slashdot reader ArchieBunker shares a report from TIME Magazine: On an evening in December 2023, 43-year-old small business owner Sarah Rosenkranz collapsed in her home in Granbury, Texas and was rushed to the emergency room. Her heart pounded 200 beats per minute; her blood pressure spiked into hypertensive crisis; her skull throbbed. "It felt like my head was in a pressure vise being crushed," she says. "That pain was worse than childbirth." Rosenkranz's migraine lasted for five days. Doctors gave her several rounds of IV medication and painkiller shots, but nothing seemed to knock down the pain, she says. This was odd, especially because local doctors were similarly vexed when Indigo, Rosenkranz's 5-year-old daughter, was taken to urgent care earlier that year, screaming that she felt a "red beam behind her eardrums." It didn't occur to Sarah that these symptoms could be linked. But in January 2024, she walked into a town hall in Granbury and found a room full of people worn thin from strange, debilitating illnesses. A mother said her 8-year-old daughter was losing her hearing and fluids were leaking from her ears. Several women said they experienced fainting spells, including while driving on the highway. Others said they were wracked by debilitating vertigo and nausea, waking up in the middle of the night mid-vomit. None of them knew what, exactly, was causing these symptoms. But they all shared a singular grievance: a dull aural hum had crept into their lives, which growled or roared depending on the time of day, rattling their windows and rendering them unable to sleep. The hum, local law enforcement had learned, was emanating from a Bitcoin mining facility that had recently moved into the area -- and was exceeding legal noise ordinances on a daily basis.

Over the course of several months in 2024, TIME spoke to more than 40 people in the Granbury area who reported a medical ailment that they believe is connected to the arrival of the Bitcoin mine: hypertension, heart palpitations, chest pain, vertigo, tinnitus, migraines, panic attacks. At least 10 people went to urgent care or the emergency room with these symptoms. The development of large-scale Bitcoin mines and data centers is quite new, and most of them are housed in extremely remote places. There have been no major medical studies on the impacts of living near one. But there is an increasing body of scientific studies linking prolonged exposure to noise pollution with cardiovascular damage. And one local doctor -- ears, nose, and throat specialist Salim Bhaloo -- says he sees patients with symptoms potentially stemming from the Bitcoin mine's noise on an almost weekly basis. "I'm sure it increases their cortisol and sugar levels, so you're getting headaches, vertigo, and it snowballs from there," Bhaloo says. "This thing is definitely causing a tremendous amount of stress. Everyone is just miserable about it."
"By the end of 2024, we intend to have replaced the majority of air-cooled containers with immersion cooling, with no expansion required," said a representative for Marathon Digital Holdings, the company that owns the mine. "Initial sound readings on immersion containers indicate favorable results in sound reduction and compliance with all relevant state noise ordinances." They did not answer questions about the health impacts their mining site was causing.

"We're living in a nightmare," said Rosenkranz. She clocked the hum at 72 decibels in Indigo's bedroom in the dead of night. "Indigo's room directly faces the mine, which sits about a mile and a half away," notes TIME. She had to be pulled from her school after she developed so many ear infections from the sound.

The report also said a resident's dog "started going bald and developed debilitating anxiety shortly after the Bitcoin mine began operating four blocks away." TIME added: "Directly next door, Tom Weeks' dog Jack Rabbit Slim started shaking and hyperventilating uncontrollably for hours on end; a vet placed him on the seizure medication Gabapentin. Rosenkranz's chickens stopped laying eggs for months. And Jerry and Patricia Campbell's centuries-old oak tree, which had served as the family's hub and protector for generations of backyard family reunions and even a wedding, died suddenly three months ago."

OpenAI and Arianna Huffington Are Working Together On an 'AI Health Coach' 25

OpenAI CEO Sam Altman and businesswoman Arianna Huffington have announced they're working on an "AI health coach" via Thrive AI Health. According to a Time magazine op-ed, the two executives said that the bot will be trained on "the best peer-reviewed science" alongside "the personal biometric, lab, and other medical data you've chosen to share with it." The Verge reports: The company tapped DeCarlos Love, a former Google executive who previously worked on Fitbit and other wearables, to be CEO. Thrive AI Health also established research partnerships with several academic institutions and medical centers like Stanford Medicine, the Rockefeller Neuroscience Institute at West Virginia University, and the Alice L. Walton School of Medicine. (The Alice L. Walton Foundation is also a strategic investor in Thrive AI Health.) Thrive AI Health's goal is to provide powerful insights to those who otherwise wouldn't have access -- like a single mother looking for quick meal ideas for her gluten-free child or an immunocompromised person in need of instant advice in between doctor's appointments. [...]

The bot is still in its early stages, adopting an Atomic Habits approach. Its goal is to gently encourage small changes in five key areas of your life: sleep, nutrition, fitness, stress management, and social connection. By making minor adjustments, such as suggesting a 10-minute walk after picking up your child from school, Thrive AI Health aims to positively impact people with chronic conditions like heart disease. It doesn't claim to be ready to provide real diagnosis like a doctor would but instead aims to guide users into a healthier lifestyle. "AI is already greatly accelerating the rate of scientific progress in medicine -- offering breakthroughs in drug development, diagnoses, and increasing the rate of scientific progress around diseases like cancer," the op-ed read.

Johns Hopkins Med School Will Be Free For Most After $1 Billion Donation (axios.com) 135

Starting this fall, most students at Johns Hopkins' medical school will attend tuition-free thanks to a $1 billion donation from billionaire Mike Bloomberg. From a report: The generous gift is intended to address "twin challenges of declining levels of health and education," Bloomberg said in a letter Monday. The donation will cover the full cost of tuition for medical students from families earning less than $300,000, Bloomberg Industries announced Monday. It will also cover living expenses and other fees for students from families earning up to $175,000.

Currently, nearly two-thirds of medical students at the school qualify for financial aid. Johns Hopkins' medical students graduate with an average student loan debt of about $104,000. The donation will also increase financial aid at some of the university's other graduate schools, including the schools of nursing and public health.

Doctors Try Controversial Technique To Reduce Transplant Organ Shortage (npr.org) 69

A controversial organ retrieval technique is gaining traction across the U.S., promising to alleviate chronic organ shortages but also sparking intense ethical debates, NPR reports. Normothermic regional perfusion, now used by half of the nation's organ procurement organizations, restores blood flow to organs after cardiac death. Proponents argue it increases viable organ supply and improves transplant outcomes. Critics, however, question whether the procedure blurs the definition of death.

Air Pollution Can Decrease Odds of Live Birth After IVF By 38%, Study Finds 56

An anonymous reader quotes a report from The Guardian: Air pollution exposure can significantly decrease the chance of a live birth after IVF treatment, according to research that deepens concern about the health impacts of toxic air on fertility. Pollutant exposure has previously been linked to increased miscarriage rates and preterm births, and microscopic soot particles have been shown to travel through the bloodstream into the ovaries and the placenta. The latest work suggests that the impact of pollution begins before conception by disrupting the development of eggs. "We observed that the odds of having a baby after a frozen embryo transfer were more than a third lower for women who were exposed to the highest levels of particulate matter air pollution prior to egg collection, compared with those exposed to the lowest levels," said Dr Sebastian Leathersich, a fertility specialist and gynaecologist from Perth who is due to present the findings on Monday at the European Society of Human Reproduction and Embryology annual meeting in Amsterdam. [...]

The study analyzed fertility treatments in Perth over an eight-year period, including 3,659 frozen embryo transfers from 1,836 patients, and tracked whether outcomes were linked to the levels of fine particulate matter, known as PM10. The overall live birthrate was about 28% per transfer. However, the success rates varied in line with exposure to pollutants in the two weeks leading up to egg collection. The odds of a live birth decreased by 38% when comparing the highest quartile of exposure to the lowest quartile. "These findings suggest that pollution negatively affects the quality of the eggs, not just the early stages of pregnancy, which is a distinction that has not been previously reported," Leathersich said. The team now plan to study cells directly to understand why pollutants have a negative effect. Previous work has shown that the microscopic particles can damage DNA and cause inflammation in tissues.
The report notes that the link between air pollution and live birth "was apparent despite excellent overall air quality during the study period, with PM10 and PM2.5 levels exceeding WHO guidelines on just 0.4% and 4.5% of the study days."

It adds: "Australia is one of just seven countries that met the WHO's guidelines in 2023, and this study is the latest to show evidence of harm even at relatively low levels of pollution."

The study has been published in the journal Human Reproduction.

Temperatures 1.5C Above Pre-industrial Era Average For 12 Months, Data Shows (theguardian.com) 119

The world has baked for 12 consecutive months in temperatures 1.5C (2.7F) greater than their average before the fossil fuel era, new data shows. Temperatures between July 2023 and June 2024 were the highest on record, scientists found, creating a year-long stretch in which the Earth was 1.64C hotter than in preindustrial times. From a report: The findings do not mean world leaders have already failed to honour their promises to stop the planet heating 1.5C by the end of the century -- a target that is measured in decadal averages rather than single years -- but that scorching heat will have exposed more people to violent weather. A sustained rise in temperatures above this level also increases the risk of uncertain but catastrophic tipping points.

Carlo Buontempo, director of the Copernicus Climate Change Service, which analysed the data, said the results were not a statistical oddity but a "large and continuing shift" in the climate. "Even if this specific streak of extremes ends at some point, we are bound to see new records being broken as the climate continues to warm," he said. "This is inevitable unless we stop adding greenhouse gases into the atmosphere and the oceans." Copernicus, a scientific organisation that belongs to the EU's space programme, uses billions of measurements from satellites, ships, aircraft and weather stations to track key climate metrics. It found June 2024 was hotter than any other June on record and was the 12th month in a row with temperatures 1.5C greater than their average between 1850 and 1900. Because temperatures in some months had "relatively small margins" above 1.5C, the scientists said, datasets from other climate agencies may not confirm the 12-month temperature streak.

Insurers Pocketed $50 Billion From Medicare for Diseases No Doctor Treated 117

A Wall Street Journal analysis has revealed that private insurers in the government's Medicare Advantage program, including UnitedHealth Group, have made numerous questionable diagnoses leading to increased taxpayer-funded payments between 2018 and 2021.

The investigation found instances where patients were diagnosed with conditions they did not have, such as diabetic cataracts and HIV, often without their knowledge. These diagnoses resulted in higher payments from Medicare to the insurers. The Centers for Medicare and Medicaid Services said they are implementing changes to ensure "taxpayer dollars are appropriately spent." The story adds: In all, Medicare paid insurers about $50 billion for diagnoses added just by insurers in the three years ending in 2021, the Journal's analysis showed.
